Ali ibn Ibrahim from his father from Ibn Abi Umayr from Hammad from Mansur: Abu Abdillah (a.s), peace be upon him, said: "When Jibrail (a.s), peace be upon him, descended with the Adhan to the Messenger of Allah (swt), peace be upon him and his family, the Messenger’s head was in the lap of (Imam) Ali (a.s), peace be upon him. Jibrail, peace be upon him, made the call to prayer and established it. When the Messenger of Allah (swt), peace be upon him and his family, awoke, He (saws) said: 'O Ali, did you hear it?' He (Imam Ali (a.s)) said: 'Yes.' He {Prophet (saws) said: 'Did you memorize it?' He (Imam Ali (a.s)) said: 'Yes.' He {Prophet (saws) said: 'Call Bilal and teach him.' So (Imam) Ali (a.s), peace be upon him, called Bilal and taught him."
